    • Calculating the Solar Heat Gain of Window Frames 

      Wright, John L.; McGowan, Alexander G. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)
      It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ...
    • A Correlation to Quantify Convective Heat Transfer Between Vertical Window Glazings 

      Wright, John L. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)
      Several correlations have been used in recent years for the purpose of calculating convective, centre-glass heat transfer rates across gas-filled interpane window cavities. These correlations are examined and their background ...
    • Overview of a Project to Determine the Surface Temperatures of Insulated Glazing Units: Thermographic Measurement and Two-Dimensional Simulation 

      Wright, John L.; Sullivan, Harry F.; Fraser, Roydon A. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)
      A collaborative research project was undertaken to generate surface temperature profiles for the indoor side of seven different double and triple-glazed insulated glazing units exposed to the ASHRAE winter design condition. ...
    • A study of insulated glazing unit surface temperature profiles using two-dimensional computer simulation 

      Wright, John L.; Sullivan, Harry F.; De Abreu, Pedro Felipe; Fraser, Roydon A. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)
      This paper describes one part of a collaborative research project, including both measurement and simulation studies, aimed at determining the surface temperature of a set of insulated glazing units (IGUs). In this study ...
    • Summary and comparison of methods to calculate solar heat gain 

      Wright, John L. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)
      Methods used to calculate the solar gain of windows (including center-glass, edge-glass, and frame) are examined and compared Particular attention is devoted to the public-domain computer programs VISION3 and WINDOW 4.1. ...
    • Thermal Resistance of a Window with an Enclosed Venetian Blind: A Simplified Model 

      Wright, John L.; Collins, Michael R.; Huang, Ned Y. T. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)
      Solar gain has a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on 1-D models is available to accurately predict the thermal ...
    • Thermal Resistance of a Window with an Enclosed Venetian Blind: Guarded Heater Plate Measurements 

      Wright, John L.; Huang, Ned Y. T.; Collins, Michael R. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)
      Window solar gain is known to have a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on one-dimensional models is available ...
    • A two-dimensional numerical model for glazing system thermal analysis 

      Wright, John L.; Sullivan, Harry F. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)
      A simple two-dimensional (2-D) numerical control volume formulation is presented that can be used to model heat transfer through a vertical insulated glazing unit. This model accounts for natural convection of the fill gas ...
